In pure population problems, a single resource is to be distributed equally among the agents in a society, and the social planner chooses population size(s) and per-capita consumption(s) for each resource constraint and set of feasible population sizes within the domain of the solution. This paper shows that a weak condition regarding the possible choice of a zero population is necessary and sufficient for the rationalizability of a solution by a welfarist social ordering. In addition, solutions that are rationalized by critical-level generalized utilitarianism are characterized by means of a homogeneity property.

From the perspective of symbolic interactionism, inner experiences—including emotions—are shaped culturally as individuals formulate events in words, and individual experiences are shaped socially as others contribute to the verbal formulation of one's experiences. Understanding cultural shaping and social negotiation of emotions requires understanding how emotion attributions arise from linguistic framings of events, and Affect Control Theory (ACT) offers a model of emotions that addresses this issue. We report tests of ACT predictions of emotions in 128 events against self-reported emotions of respondents imagining themselves in such situations. ACT predictions are found to correlate with self-reported emotions. Thus, empirical results validate ACT's postulate that emotions emerge from the personal impression that is generated in an event, along with the difference between that impression and the person's identity. In the conclusion, we discuss how the ACT formulation can enlighten interpretations of social negotiations regarding emotions.  相似文献

This research evaluates determinants of sales organization effectiveness in a sample of British companies, and contributes to an important new research stream by following recent empirical studies in the USA and Australia. We discuss a model of sales organization effectiveness determined by salesforce outcome performance and behavioural performance, as well as by the use of a behaviour-based control approach. Sales territory design is also considered as a particularly important managerial variable, which has received little analytical attention in the traditional literature, but which appears to be an important influence on the effectiveness of the sales operation. Our exploratory path analytical model suggests that sales territory design has a large effect on sales organization effectiveness both directly, and indirectly through its relationship with salesforce behavioural performance. These findings are somewhat different to those in similar studies in other countries, and suggest some important implications for managers as well as for researchers in this field.  相似文献

Given the great historical distance between scientific explanation as Aristotle and Hempel saw it, some important similarities and differences between the two approaches are examined and appraised, especially the inclination to take deduction itself as the very model of scientific knowledge: an inclination we have good reasons to reject.  相似文献

The branching structure of inflorescences of the cultivated strawberry ( Fragaria × ananassa Duch.) is very variable. This paper demonstrates that some aspects of this variability are well described by a simple stochastic model of branching that has two adjustable parameters. The model is shown to provide a good fit to data from a set of almost 700 inflorescences of the cultivar Elsanta, collected over two successive years. For one parameter the maximum likelihood estimator is a moment estimator which is fully efficient even if the detailed branching structure of the inflorescences is not recorded. This parameter provides a convenient summary of branching vigour. The maximum likelihood estimator of the second parameter must be determined iteratively and can be quite inefficient unless the full branching structure is recorded. The model demonstrates that branching structure is affected by the order in which inflorescences emerge on the plant.  相似文献

Weighted Approximations to Continuous Time Martingales with Applications   总被引:1,自引:0,他引:1  
A weighted approximation to a sequence of continuous time martingales by a time transformed Wiener process is established. The basic tool of proof is the Skorohod imbedding for martingale difference sequences. As an application of the main result a useful weighted approximation to the randomly weighted uniform empirical process is derived. A number of other applications are also discussed.  相似文献

This article discusses the major contributions (Krumboltz & Worthington, 1999; Lent, Hackett, & Brown, 1999; Savickas, 1999; Swanson & Fouad, 1999) to this special issue of The Career Development Quarterly on the application of career development theories to the school-to-work transition. Common thematic elements in these 4 articles include a focus on the individual who faces the transition from high school to work and an emphasis on the developmental aspects of the transition. The article concludes with a cautionary recommendation that theory-building efforts derived from the individual experiences of work-bound youth ought to be included in theoretical and intervention initiatives to facilitate the school-to-work transition.  相似文献

Segregation and Mortality: The Deadly Effects of Racism?   总被引:10,自引:0,他引:10  
Elevated rates of mortality for African Americans compared to whites, coupled with the persistence of high levels of racial residential segregation, have directed attention to the structural manifestations of racism as potentially important pathogens for health. Using national mortality and census data for 1990 and a measure of black social isolation from whites, we examine the association between residential segregation and mortality in 107 major U.S. cities. Our analyses revealed that black social isolation tended to predict higher rates of mortality for African American males and females, although the strength of the association varied by cause of death. Socioeconomic deprivation explained a modest part of this association for black males but not for black females. Our analyses also found that a positive association between social isolation and mortality was more pronounced, for both blacks and whites, in cities that were also high on the index of dissimilarity. These findings highlight the need for research to identify the specific mechanisms and processes that link residential environments to adverse changes in health status.  相似文献

From 1991 through 1998, during the turmoil of independence and transition to a democracy and free-market economy, the authors established the first social work education programme in Lithuania and assisted Lithuanian professionals to assume responsibility for the programme. This article supplies an initial general and conceptual narrative and analyses some of the factors that influenced the development of the programme and a practice model to address conditions in Lithuania.  相似文献

How does the structure of the world economy determine the gains from participation therein? In order to answer this question, we conduct a state of the art network analysis of international trade to map the structure of the international division of labor (IDL). We regress cross-national variation in economic growth on positional variation and mobility of countries within the IDL from 1965 to 2000. We find that the highest rates of economic growth occurred to countries in the middle of the IDL over the course of globalization. Second, we find that upper tier positions in the IDL are converging with each other, but diverging from the lower tier. This suggests that the mechanism underlying the rapid economic growth in intermediate positions was their uniquely high rates of upward mobility, in turn a function of their middling position. Taken together, these findings suggest that a country’s long-term economic development is conditioned by its position in the IDL.  相似文献
